Comparing Numbers
To compare two numbers we first consider the digit on the left of each number.
Example: Compare the numbers 53 and 35. Which number is bigger?
Which number is smaller?
5 in 53 is 5 tens.
3 in 35 is 3 tens.
5 tens is more than 3 tens
Hence 53 is greater than 35 or 53 > 35
And 35 is smaller than 53 or 35 < 53
1. Compare the numbers. Write the correct symbol <, >, = .
(a) 15 ______ 16
(b) 22 ______ 11
(c) 18 _____ 8

2. Compare the numbers. Write the correct symbol <, >, = .

Place Value Dice Game
Activity 1: Constructing the smallest number.
The objective of this game is to determine the smallest number possible when 3 diceare rolled.
Materials required: 3 dice, place value recording sheet (see Table 1 below)
Number of players: 4
Procedure:
1. This game requires 4 players, A, B, C and D. The responsibility of player A is to
roll the dice, verify the players’ answers and record the scores of the players B,
C and D in the score sheet below. A correct answer obtains a score of 10 marks.
An incorrect answer gets zero mark.
2. A place value recording sheet (Table 2) is given to each of the players B, C and D.

4. Player B, C and D construct the smallest 3-digit number from the dice and
record it in their respective sheets.
5. Player A rolls the 3 dice 4 more times. Each time the students have to construct
and record the smallest number in their place value recording sheet.
6. The player with the highest score is the winner.
Activity 2: The game can be modified to find the greatest 3-digit number.

We can represent number four as follows:
4 is double 2
4 is 1 less than 54 is half of 8
In the same way, we can represent five as follows:
5 is half of 10
5 is one more than 45 is double 2 and 1
Consider the representations of eight:8 is 5 and 3 more8 is 5 + 38 is 6 + 28 is 2 less than 10
8 is double 48 is 4 groups of 2

Subtraction by splitting
Often, we can perform subtraction by splitting the number being subtracted.
Example 1 Consider 12 – 5We split 5 such that it contains the number 2.5 = 2 + 3First we subtract 2. Then we subtract 312 – 2 = 1010 – 3 = 7Thus, 12 – 5 = 7.
Example 2 43 – 7
We split 7 such that it contains the number 3.
7 = 3 + 4
First we subtract 3. Then we subtract 4.
43 – 3 = 40
40 – 4 = 36
Thus, 43 – 7 = 36.
4. Workout the subtraction by spliting.

(b) 51 – 8 (d) 51 – 9

Subtraction involving 9
To subtract 9 from a number, we first subtract 10, then we add 1.
Example 1 21 – 9
9 is one less than 10
We subtract 10 and then add 1.
21 – 10 = 11
11 + 1 = 12
Thus, 21 – 9 = 12.
Example 2 47 – 9
We subtract 10 and then add 1.
47 – 10 = 37
37 + 1 = 38
Thus, 47 – 9 = 38.
